[cache] Remove unused `node_reset`.

* src/cache/ftcmru.h (FTC_MruListClassRec): Remove `node_reset` field.
* src/cache/ftcbasic.c (ftc_basic_{image,sbit}_family_class): Ditto.
* src/cache/ftcmanag.c (ftc_face_list_class): Ditto.
(ftc_size_node_reset): Remove function.
* src/cache/ftcglyph.h: Fix comment.
